Trz calling SetBuddy of the spin control specifying yout edit. Something like:
my_spin.SetBuddy(&my_edit);

You have at least 3 possibilities:
1. as someone already mentioned, use the auto-buddy feature (set that to true in the dialog editor for your spin button and make sure the spin comes right after the edit in tab order)
2. specify a control variable too for your edit button (CEdit) and pass that to SetBuddy
3. use GetDlgItem() to get a pointer for your edit control and feed that to the SetBuddy call (presuming you already have a CSPinButtonCtrl type member assigned to your spin control.

i have used GetDlgItem(ID name) and then what i have to pass in the SetBuddy function.

Sorry, i got mixed up there, i thought you had the double for your spin button, not your edit, i will edit my previous post and then check it again.

Ok No problem,

i have created control variable for spin control already.

m_voltspin.SetRange(0,50);

i have memeber variable for edit box in that i have declared as double.

i have set true in the spin control properties
(Auto Buddy), problem is am not able to see the values in the dit box when i press up / down the spin control, it is updating somewhre.

There's a spin button style called "Set buddy int" (UDS_SETBUDDYINT), make sure that is set for your spin button.

do u have any idea

Actually i have Rich text contol present in my dialog. I will get messages from the board, when the messages exceeds the size of the window, scroll bar automatically comes because of i had set the scroll bar(Vertical scroll bar) property of Rich Text Control.

My question is, when message exceeds the window size, the scroll bar automatically goes up. i don want scroll bar to move up rather it should go down, then only i can able to see latest updates form the board at time itself.

Thanks in advance,

Thanks,

Balaji

Probably you have "Auto buddy" property set and your TAB order is not properly set.

As some one has already suggested you can set buddy window using SetBuddy member function of CSpinButtonCtrl class.
I hope it helps.

In the resource editor:

set the spin control's tab order immediately after the edit control

set the spin control's alignment property to Right (or Left)

check both the "Auto buddy" and "Set buddy integer" checkboxes

In the dialog's OnInitDialog() method, set the value via the edit control's SetWindowText() method.

Hi I m working on Pocket PC application using C++ (Win 32). and i want to load multiple image on other single bitmap image (treated as a container of images) . and the new images are the child of the single bitmap image. and these images must be treated as a single bitmap image. i m trying to do this using offScreenBuffer , CreateCompatibleBitmap of Win 32 C++.
Please suggest how i do this.

creating dialogs in a loop

7-Dec-08 22:12

Well, i haven't written any progs for PocketPC but as far as i know this mainly works the same way as it does on the desktop platform, so what you should do is to create 2 memory DCs, select your target bitmap (the one you want to put the others on) in the first one and then the other bitmaps you want to put on the first one one by one into the second one and use BitBlt. So something like:

HDC TargetDC, SourceDC;
TargetDC = CreateCompatibleDC(NULL);
SourceDC = CreateCompatibleDC(NULL);
HBITMAP OriginalTargetBitmap = SelectObject(TargetDC, TargetBitmap);
...
//Put this into a loop that walks thorough all the bitmaps
HBITMAP OriginalSourceBitmap = SelectObject(SourceDC, CurrentSourceBitmap);
BitBlt(TargetDC, X, Y, CurrBmpWidth, CurrBmpHeight, SourceDC, 0, 0, SRCCOPY);
SelectObject(SourceDC, OriginalSourceBitmap);
...
SelectObject(TargetDC, OriginalTargetBitmap);
DeleteDC(SourceDC);
DeleteDC(TargetDC);

Hi everybody,

I am trying to create dialogs in a loop.
I am having pointer to each dialog and resource id.
Problem is while creating an object of that dialog using new operator.
As new requires the typename which i am unable to provide in a loop.

Please refer the code below.

DlgA *pDlgA;
DlgB *pDlgB;

typedef struct tagDLG_INFO
{
CDialog *pDlg;
DWORD dwDlgID;

} DLG_INFO, *P_DLG_INFO;

DLG_INFO arrDlgInfo[2] =
{
{pDlgA, IDD_A},
{pDlgB, IDD_B}
};

for (DWORD dwLoopCount = 0; dwLoopCount < 2; ++dwLoopCount)
{
arrDlgInfo[dwLoopCount].pDlg = new XXX; //(How to provide typename in a loop).
arrDlgInfo[dwLoopCount].pDlg->Create(arrDlgInfo[dwLoopCount].dwDlgID, this);
}

I tried using macros, templates, RTTI, typeinfo,
but i did'nt find any proper solution.

Thanks in advance.

If not needed to create a modaless dialog then better to call DoMadal function of CDialog class to create Modal Dialog.

I am sorry that u didn't get the question.
what i want to do is similar to the following,

float *pf;
float *pf = new float; (This is the normal case where float is the typename passed to new operator).

(Now consider our problem)
int *pi;
char *pc;

If i have such many different types of pointers.
And i want to create memory to that respective pointer with it's respective type in loop.
So how am i able to provide typename to the new operator generically in a loop.

Does this work for you?

arrDlgInfo[dwLoopCount].pDlg = IDD_A == arrDlgInfo[dwLoopCount].dwDlgID ? new pDlgA(this):new pDlgB(this);

Could also check for NULL

Your solution is good.
But i had given a sample of code.
What actually i want to do is to create around 20 dialogs of different types.
The resource i can have for this is the array of DLG_INFO.
For acheiving this we can extend or add more members to DLG_INFO.

Thanks.

"around 20 dialogs of different types"

which user should use such messy GUI. Dead | X|

This is confusing and unusable, you better rethink your software architecture Blush | :O

PS: I have written a project which a bunch of modeless dialogs, which will be shown if a vertical tab got selected. It got to messy and crappy, but my boss wanted it.
